OpExcEccentric Control Valve

1OPTIMUX

IntroductionThe OpExc is a high performance rotary control valvecharacterized by its eccentric and innovative plug. TheOpExc has been designed for optimal performance in awide array of process control applications, such as: Lowpressures, high Cv's, slurry fluids, Oil&Gas, etc. The OpExcoperates comfortably under high shut-off pressure dropconditions as much as 100 bars (1450psig) and operatingtemperatures from -100C to 430C (-150F to 800F).

Its eccentric plug offers excellent and extended rangeabilityof 160:1 compared to 50:1 in a globe valve and 20:1 in themajority of the butterfly valves. The robustness of theOpExc reduces significantly common problems caused byknocking and battering.

The OpExc has low hysteresis as well as high strength onactuation and accurate control enhanced by the utilizationof our piston actuator, which grants additional robustness to

the complete assembly when compared to other actuatorsfound in the market.

The OpExc has a very robust "not-through" shaft anchoredby a fixed post in the other end, and which allows foruninterrupted flow of fluids. This characteristic increasesCv's up to 70% when compared to other valves displayingrotary plugs.

The OpExc is manufactured in diameters of 1" to 12" andcomes in two types of bodies: With flanges (ANSI class 150,300, and 600) and flangeless (ANSI class 150 and 300).The OpExc ability to handle large Cv's in normal or severeapplications is unmatched by any other valve design in theOil, Chemical, and Pulp & Paper industries. All theseattributes make the OpExc the choice for many processcontrol engineers.

Adjusted Closing, Low Maintenance

The valve configuration warrants a high flow capacity. In theopen position (figure 2), the plug travels away from thecenter of the flow and direction, the shaft as well, stays outof contact.

As the valve opens and the plug turns away from the seatthe possibility of knocking or battering is greatly reduced.The eccentric shape of the OpExc has zero breakout torquewhich allows the use of smaller actuators thus reducingcosts and maintenance time.

High Cv, Initial Zero Dynamic Par

The eccentric plug with double separation turns towards theseat up to a given angle that eliminates skidding over its ownsurface (figure 3). This type of design reduces wear of theseat and consequently the need for frequent maintenanceand making the OpExc one of the highest performancevalves for severe applications.

Due to the fact that plug and shaft do not constraint flow, itproduces one of the highest CV's in the industry.

Metal seats fulfill shut-off requirements for ANSI Class IVand ANSI Class VI, using soft seats.

SeatsThe OpExc amply serves the demands of different flows.The internals are supplied with 100%, 70% in valvesdiameters from 1" to 12" and 40% in valves from 1" to 6".

DependabilityThe shaft of the OpExc has been designed and built robustand oversized as to eliminate any possibility of failure. Itsdesign offers ample contact between the shaft and itsbearings, this way reducing unnecessary wear andincreasing the life expectancy of the valve. The plug madeof 17-4pH and hardened by thermal treatment providesexcellent shut-off characteristics that broadens itsapplications such as flashings, corrosive fluids, mediumcavitations, and water steam, in general.

The "not-through" shaft design eliminates obstructions to thefluids. When the valve is open, the fluid is not deviatedtowards the seat or to the seat retainer, which gives theOpExc high dependability even after many years ofintensive use.

The union between shaft and plug is made via a welladjusted and precise splined system, which helps toeliminate the traditional pins or other mechanical elementsconducive to corrosion and/or damages caused byvibrations.

The strong seat allows the utilization of the OpExc underhigh differential pressures. For severe applications the plugand its seat can be fabricated with a surface partially ortotally in stellite # 6.

In addition the packing set is placed away from the effects ofthe fluid, increasing its life under either low or hightemperatures.

The typical maintenance cycle for the OpExc surpasses 5years, and its life expectancy surpasses 20 years. Our OpTkactuators have a life superior to one million cycles, makingthe OpExc the most dependable valve.

Performance CV capacity and rangeability of 160:1 far surpasses anyother eccentric plug valve in the market.

All these characteristics have made the OpExc a superior valve within its category.

ExLPackings

9OPTIMUX

The EXL rotary valve is built with a large packing box whichgives a longer service life to the packing assembly. The EXLPacking box design allows for the use of a large number ofpacking system options, and fully complies with the mostdemanding fugitive emission control regulations in modernindustrial processes.

Standard Packing The EXL standard packing set is composed by PTFE “V”rings, Figures 8A and 8B. The PTFE “V” rings are the mostused packing system since their introduction, providingexceptional tight sealing. They provide a very low frictioncoefficient, good mechanical resistance and excellentresistance to corrosion. The PTFE “V” rings are the mostcommon application choice for gasketing material.

The PTFE “V” rings are used within temperature ranges of -150º to 450°F (-101 to 232° C). High Temperature PackingThe EXL formed packing rings, Figures 9A and 9B, is analternative choice whenever the operating temperatureexceeds that determined for the use of PTFE “V” rings. Thematerials employed in the formed packing rings of the EXLare braided PTFE for use in temperatures up to 500°F(260°C) and Grafoil for use in temperatures up to 752°F(400°C). The Grafoil formed packing rings are an excellentchoice whenever packing is subjected to high operatingtemperatures, however it should be noted that the demandof high forces required to achieve a tight sealing results in asignificant friction increase forces as the valve plug turns.

Special PackingThe PT type packing set, Figure 10A, is composed by a setof “V” type rings under compression by an assembly of discsprings that result in a ”live-loading” effect. This systemachieves a sealing level of below 500 ppm. The PT typepacking combines the superior virgin PTFE “V” rings qualitywith the PTFE “V” rings combined with carbon filamentwound. The PTG type packing, Fig. 10B, is composed of anadvanced packing set that is capable of keeping a sealingrate very below 500 ppm (at a 10 ppm step rate). The PTGpacking set is composed by the combination of PTFE “V”rings with carbon filament wound and Kalrez® “V” rings, anadvanced material that provides a superior performance tothe packing set. For temperatures higher than 450°F (232°C) the PTG XT packing set is employed. This type ofpacking utilizes Zymax® rings instead the PTFE/carbonrings.
